The R911281243 (MHD115B-024-NG0-RN) is a brushless servo motor from the MHD series with a permanent magnet-excited design. It features a 192 mm flange size, 180 mm centering diameter, and motor size 115. The motor incorporates lifetime-lubricated bearings, a plain shaft with shaft seal, and utilizes liquid cooling with natural convection to manage thermal conditions. It is equipped with a digital servo feedback encoder (HSF) for relative position detection, and delivers 50.0 Nm continuous torque at standstill. The housing is fully sealed to IP65 standards. No holding brake is integrated.

How does the plain shaft design affect coupling with the load?

The plain shaft enables precise alignment and low backlash when used with keyed or clamping couplers. The design minimizes vibration and enhances accuracy in motion transmission.

Why is digital servo feedback important for precision control?

The digital servo feedback system provides accurate position and velocity data to the controller. The result is improved dynamic response and tighter speed regulation in automation tasks.

What advantage does having a holding brake provide during vertical load applications?

The holding brake secures the load when power is cut or during emergency stops. The design ensures mechanical safety and prevents unintentional axis movement.

How does a relative position detection system impact homing routines?

The relative encoder requires a homing sequence after each power cycle to establish a reference position. The setup ensures repeatable motion accuracy after initialization.

What installation factors should be considered for right-side power connection orientation?

The right-side power connector allows convenient cable routing in compact machinery layouts. The installer must ensure adequate clearance and strain relief to prevent cable stress.
